ンサ部分が絶縁破壊するのを防ぐことができた。In the prior art, a multilayer capacitor capable of efficiently producing a capacitor element shape from a wound type and an end-faced oval type has been reduced in size and price, and a safety device,
We have provided highly safe metallized film capacitors by providing thermal fuses and the like. The laminated metallized film capacitor is composed of a metallized film 20 and a non-metallized film 2.
1 or a metallized film 20 is superimposed and wound and laminated on a metal bobbin, metal spraying is performed on both end surfaces of the film to form a metallikon 24, and further heat aging to remove a metal bobbin (not shown). To form a large capacitor, which is cut into a predetermined size with a cutting blade to form a single capacitor. Further, the security mechanism is disclosed in JP-A-61-2313,
As disclosed in JP-A-280410 and JP-A-6-310368, a fuse portion is formed on the metal-deposited electrode 12, or the metal-deposited electrode 22 is divided into a plurality of pieces to make the entire capacitor a collection of minute capacitors. Even if dielectric breakdown occurs in one part of the entire capacitor that functions as a dielectric, the metal deposition electrode of the part involved in the dielectric breakdown part is electrically disconnected from the entire capacitor and released. However, it is possible to prevent dielectric breakdown of other minute capacitor portions. However, the metallized film using the finely divided metal deposition electrodes 22a and 22b as a security mechanism as shown in FIG. 3 and FIG. 4 is not used for a laminated metallized film capacitor, and is not used for a wound type capacitor or an end face oval. Used only for type capacitors. this is,
Since the area of the metal deposition electrode in one layer of the laminated metallized film capacitor is small, FIGS.
This is because it is not necessary to divide the metal deposition electrode into a plurality of pieces as in the above. In addition, a safety device and a safety device are provided with a mechanical weak point in a conductive portion inside the outer container in advance, and the mechanical weak point is separated by an increase in the internal pressure of the outer container, and the electric power to the multilayer capacitor is cut off. This shuts off the supply of energy. In the conventional example shown in FIG. 5, a fuse portion 23 is formed on at least one of the two metal-deposited electrodes 22 facing each other, and a double-sided metallized film 20 serving as a security mechanism is provided. Chemical film 2
1 and rolled and laminated on a metal bobbin, zinc metal spraying is applied to both ends of the film to form metallikon 24, and further heat aging, and the metal bobbin (not shown) is removed to form a large ring. A capacitor base was cut with a cutting blade to obtain a laminated metallized film capacitor. With this laminated metallized film capacitor, miniaturization and cost reduction can be achieved.
Even if a dielectric breakdown occurs in a part of the dielectric film in one place of the entire capacitor, the metal deposition electrode of the part involved in the dielectric breakdown is electrically isolated from the entire capacitor. To prevent the other capacitor parts from dielectric breakdown.

が困難であるという問題点も有していた。In order to obtain a laminated metallized film capacitor, the wound and laminated large ring capacitor matrix is cut into a single capacitor with a cutting blade. Instead, the cut surface is insulated by melting the film end surface of the element cut surface with the resistance heat of the cutting blade. However, in the conventional example (FIG. 5),
When insulation of the cut surface is not properly obtained or an abnormal voltage is applied in actual use, dielectric breakdown easily occurs at the cut surface, and the dielectric breakdown portion becomes the cut surface. The security mechanism provided with the fuse portion 23 that passes through the electrode margin portion 25 as in the conventional example is difficult to operate, and finally has a problem that the entire capacitor is destroyed with smoke or ignition. Further, since the cut surface of the element is insulated by melting the end face of the film by the cutting blade, the cutting withstand voltage level is very low, and only a capacitor having a low rated voltage can be designed. For this reason, a capacitor having a high rated voltage has a problem that an efficient production method cannot be obtained unlike a wound type, and it is difficult to reduce the size and the price.

Are partially bridged with each other and have a mesh pattern electrode connected via a fuse section that crosses the margin section.The insulation of the cut surface due to the cutting process is not good, or abnormal voltage in actual use However, even if dielectric breakdown occurs in one part of the element cut surface that functions as a dielectric, the micro-deposited electrode of the part involved in the dielectric breakdown part is electrically isolated from the entire capacitor and released, and the other Since the dielectric breakdown of the minute capacitor portion can be prevented, the capacitor does not break down due to smoke or ignition. In addition, even if a capacitor is used at a high voltage, since a metallized film having a security mechanism using a mesh-shaped pattern electrode as described above is used, even if a dielectric breakdown occurs at a voltage weak point portion of an element cut surface, The micro-deposited electrode of the part involved in the dielectric breakdown part is electrically cut off from the entire capacitor and separated, preventing the other micro-capacitor part from being broken down. Since it is electrically disconnected from the entire capacitor and separated, the insulation distance between the cut surface of the element and other minute capacitor portions can be obtained.
Therefore, it is possible to maintain the insulation of the element cut surface enough to withstand the high voltage design.

ある。From Table 1, it can be seen that all of the conventional laminated metallized film capacitors broke down with smoke due to dielectric breakdown at the cut surface of the element, whereas all of the capacitors of the present embodiment were secured. The mechanism operated and did not lead to destruction with smoke or ignition. In this embodiment, at least one of the two metal-deposited electrodes 2 and 2a opposed to each other has a plurality of finely-divided finely-deposited electrodes, and the fuse portion partially crosses the margin portion 3 with each other. Since the security mechanism uses the mesh pattern electrodes connected in step 4, even if a dielectric breakdown occurs at a portion of the multilayer capacitor element cut surface that functions as a dielectric, a portion involved in the dielectric breakdown portion This is because the electrode was electrically disconnected from the entire capacitor and separated, thereby preventing the other minute capacitor portions from dielectric breakdown. Next, a voltage of AC 400 V was applied to the capacitor of the present example in an atmosphere of 70 ° C. to conduct an energization test. As a result, the capacity reduction rate (%) is shown in FIG. From FIG. 2, the capacitor of the conventional example has a large capacity reduction rate (%) of -13.0 (%) after 1000 hours (H) from the start of the test, whereas the capacitor of the present embodiment has a capacity of -3. 0 (%) and excellent life characteristics were obtained. This is because, in the present embodiment, the fuse portion 4 crosses the margin portion 3 between the minute vapor deposition electrodes subdivided into a plurality of at least one of the two opposite metal vapor deposition electrodes 2 and 2a. Since a metallized film is used as a security mechanism using connected mesh-shaped pattern electrodes, even if a dielectric breakdown occurs at the voltage weak point on the cut surface of the element, the micro-deposited electrode involved in the dielectric breakdown part is not affected. Electrically cut off from the whole capacitor and released, preventing other small capacitor parts from dielectric breakdown, and the micro-deposited electrode on the cut surface of the element is electrically cut off from the entire capacitor and released Therefore, it is possible to obtain an insulation distance between the element cut surface and another minute capacitor portion.
